WATERPROOF SHOE.

Specification of Letters Patent.

Patented Jan. 24;, 1911.

Application filed April 30, 1910. Serial No. 493,116.

To all whom it may concern:

Be it known that I, SILAS H. Ynnnns, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a certain new and useful Improvement inVaterproof Shoes, of which the following is a specification.

My invention relates to a new and useful improvement in water proofingshoes and the composition for accomplishing this result,

and has for its object to produce a composition of matter and so applythe same to a fabric which is to be stitched into the shoe so as toprevent the passage of water through the sole or around the stitching tothe inside of the shoe.

With these ends in view, this invention consists in the details ofconstruction and combination of elements hereinafter set forth and thenspecifically designated by the claim.

In order that those skilled in the art to which this invention a)pertains may understand how to make an use the same, I will describeits construction in detail, referring by letter to the accompanyingdrawing forming a part of this specification, in which Figure 1 is across section of a shoe showing my improvement applied thereto. Fig. 2,a similar view of a slightly modified form of my improvement.

In carrying out my invention, I use any suitable fabric or othermaterial indicated at A, which is generally termed an insert, and afterwater proofing this material I secure it upon the upper surface of thesole B between said sole and the welt C by the stitches which securesaid welt to the sole. It will be noted that the inner edge of the WeltO is scarfed. This will protect the foot of the wearer from moisturewhich would otherwise pass through the sole and gain access to theinside of the shoe, and as the composition with which I treat the fabricA is such that it closes upon the stitching, no moisture can pass to theinside of the shoe around these stitches. This composition consists ofparaffin having a sufficient amount of coloring matter added thereto,said coloring matter being solvent in the paraffin.

In applying the composition to the fabric the former is melted in awater jacketed vessel, the fabric dip ed in the composition while thelatter is rot, and after being removed is dried and is then ready foruse, before described.

1) represents the lining of the shoe having that portion which is inproximity to the sole water proofed so as to protect the foot frommoisture which might pass through the leather of the upper.

In Fig. 2 I have shown a slightly modified form of my invention in whichI turn the lining under the welt, as indicated by E so that said liningwill be situated between the welt C and the insert A, it beingunderstood that said lining or a portion thereof has first been waterproofed.

I have found in practice that that portion of av shoe having myimprovement applied thereto will absolutely prevent the foot of thewearer from becoming moist regardless of how long the shoe may beexposed to water.

Of course I do not wish to be limited to the exact details ofconstruction here shown as these may be varied within the limits of theappended claim without departing from the spirit of my invention.

Having thus fully described my invention, what I claim as new anduseful, is-- A shoe comprising a sole, an upper, 21 waterproof insertsuperimposed on the sole, a welt stitched to said sole and insert andhaving its inner ed e scarfed, and a lining for said upper, saicI liningbeing doubled out-- wardly beneath the welt, stitches through theabutting upper and Welt and through the main and doubled portion of thelining.

In testimony whereof, I have hereunto affixed my signature in thepresence of two subscribing witnesses.
